3-Deoxysappanone B has vasorelaxation effects, it can mediate endothelium- independent vasodilator action in rat thoracic aortic rings.
Pachyaximine A possesses significant antibacterial activity against Escherichia coli, Staphylococcus aureus, Corynebacterium diphtheriae and Corynebacterium pyrogenes. (-)-Pachyaximine A demonstrates significant activity as antiestrogen binding site (AEBS)-inhibitory agents, and potentiates significantly the antiestrogenic effect mediated by tamoxifen in cultured Ishikawa cells.
Axillaridine shows significant activity as antiestrogen binding site-inhibitory agents. The complexation of AChE with Axillaridine-A, results in the reduction of gorge size due to interaction between the ligand and the active site residues.
6,8-Diprenylorobol possesses weaker anti-H. pylori activity, it may be a useful chemopreventive agent for peptic ulcer or gastric cancer in H. pylori-infected individuals; it is evaluated against the AIDS-related opportunistic fungal pathogens, Candida albicans and Cryptococcus neoformans. 6,8-Diprenylorobol shows anti-estrogenic activity comparable to that of 4-hydroxytamoxifen, a typical estrogen receptor (ER) antagonist. 6,8-Diprenylorobol shows promising cytotoxic effects toward HL-60 cells (IC50 4.3 ± 0.7 to 18.0 ± 1.7 uM), it also may be a possible candidate for the treatment of neurodegenerative diseases. 6,8-Diprenylorobol has antioxidant activity, it can reduce A2E photooxidation in a dose dependent manner.
Tracheloside significantly decreases the activity of alkaline phosphatase (AP), an estrogen-inducible marker enzyme, with an IC(50) value of 0.31 microg/ml, a level of inhibition comparable to that of tamoxifen (IC(50) = 0.43 microg/ml).
